Three-roll plate rolling machine for large ships

Abstract

The invention relates to a large-scale marine three-roller bending machine. A bending machine rack is installed on the upper surface of a bending machine base; an upper roller flexibility compensation module, an upper roller and a lower roller are sequentially installed in the bending machine rack from top to bottom; a supporting roller module is installed on the bending machine base; the upper roller and the lower roller are connected with upper and lower roller driving modules respectively; a spring support frame is arranged behind the bending machine rack; the interior of the spring support frame is connected with a plate auxiliary pressure roller rack and a plate auxiliary pressure roller through springs; a second hydraulic cylinder and a second hydraulic cylinder base are installed on the lower sides of the two sides of the spring support frame; the second hydraulic cylinder base is fixedly connected to the bending machine base; a plate auxiliary supporting module is arranged behind the spring support frame and installed on a guide rail seat; the guide rail seat is matched and in guiding connection with a guide rail fixed to the bending machine base; the back end of the guide rail seat is connected with a first hydraulic cylinder which is installed on a first hydraulic cylinder seat; and the first hydraulic cylinder seat is fixed to the bending machine base. The large-scale marine three-roller bending machine can greatly improve the rolling accuracy of plates.

Description

technical field [0001] The invention relates to a plate rolling machine, in particular to a three-roll plate rolling machine used for large ships. Background technique [0002] The plate rolling machine is an important equipment in plate processing, and the large-scale marine three-roll plate rolling machine is one of them, which is an indispensable key equipment in the shipbuilding industry. When the current large-scale marine three-roll plate rolling machine rolls ultra-wide and ultra-long plates, in order to ensure the working precision requirements of the rolled workpiece, the general method is that the operator must observe the end of the plate with the naked eye when feeding the plate. The relative position of the work roll of the plate rolling machine is to ensure that the end of the plate is parallel to the axis of the work roll of the plate rolling machine. This method often has large errors and low efficiency. When rolling ultra-long plates, due to the vibration o...

Problems solved by technology

The straightness of the ultra-wide sheet is seriously out of tolerance due to comprehensive deformation during rolling, which directly affects the accuracy of the sheet rolling. At present, the common method is to use the upper roller to adjust the idler for deflection compensation, but the existing idler device cannot be very ok fix this

Because the rolling of the plate needs to meet certain precision requirements, the market urgently needs a low-cost, easy-to-operate large-scale marine three-roll plate rolling machine, but there is no such equipment on the market at present.
